Dolomite Develops Leading Edge Etching Technology Enabling Chip Design Similar to Porous Rock Structures
(Nanowerk News) Understanding the full characteristics of fluid
flow through porous structures, such as rock, is essential for applications including oil
extraction from petroleum reservoirs, environmental testing and groundwater
analysis. However, fluid flow through porous media is very complex and difficult to
analyse. The pore space within the rock is not only difficult to access but often
characterised by parameters like connectivity and tortuosity which are very difficult to
measure and quantify. Furthermore, the flow is influenced by complex interactions
between the fluids themselves and the geometry or surface of the pore space.
By using a new etching technology, Dolomite, a world leader in microfluidic
design and manufacture, can design microfluidic chips with channel
geometries similar to porous rock structures featuring a variety of wide and
narrow channels. The channel geometry can be custom made to represent the
exact structure required.
The microfluidic chip offers excellent access for optics and full visualisation of the fluid
flow allowing fast analysis. Operating over a wide temperature (-15°C up to 250°C)
and pressure range (up to 100bar), the glass device offers outstanding chemical
resistance allowing a broad range of solvents and chemicals to be used.
